You need to pass stream resource from "gzopen" as first parameter
of "gzread", not path to the file.

Same again. (This time you tried to pass zipped data to gzread instead
of handle given by "gzopen".)

You can't remove remote file. "Unlink" works only on local files.


It could be something like:

$gz = gzopen( "http://wget-mirrors.uceprotect.net/uce-pfsm-1/access.gz", "r" );
$relayblacklist = gzread( $gz, 10000 );


but "gzopen" does not support HTTP (or FTP). It works only on local files.

There is a way to solve the problem (found in "gzopen" user notes on PHP
manual pages) using "fopen" and URL wrappers:

$fp = fopen( "compress.zlib://http://wget-mirrors.uceprotect.net/uce-pfsm-1/access.gz", "r" );
$relayblacklist = gzread( $fp, 10000 );
